Holiday let does not allow dogs…

[ChristmasCameEarly]

…but it states twice on the booking that the owner stays there and does have a dog, that you cannot complain afterwards that there was ‘dog paraphernalia’ in the house?!

Aside from the fact that ‘paraphernalia’ is almost always applied sexually, if there’s clear warnings (including on the booking email!!!!) that the owner has a dog and so the property is not suited to those with dog allergies or sensitivity, surely if you have such allergies or someone you are bringing with you does then you would not book?!

YABU: they have a right to book.
YANBU: they are idiots and didn’t read the note properly.

Hi OP - your property, your rules

i suggest you send a ‘thanks for booking’ message with important info like check out time etc ‘ put the dog allergy bit in there … give eg 48 hours to cancel which is plenty for someone to read your email

I have a holiday cottage that operates on a similar premise

So you also say dog-free but you live there at times with a dog?

It's their home, they can say what they want. Our holiday let is our guest house in our property boundary, we have a dog and a cat but the let is dog free - i don't want dogs next door, attacking my cat or winding up my dog, I don't want the hassle of cleaning up dog hair, muck, chew or urine. Sorry, choose somewhere actively dog friendly.
Bit weird they have dog paraphernalia (not in ANY WAY sexual), because when if I saw that I would assume it was dog friendly (also I think holiday let's should be as clean and clear of personal stuff as possible) but again - their house.
